Guess Who's Bringing Attention to Sexual Assault at the Oscars?

No, really:

Vice President Joe Biden will join pop star Lady Gaga on stage at the Oscars on Sunday to spotlight the issue of campus sexual assault.

Biden will introduce Lady Gaga’s performance of “Til It Happens to You,” a nominee for best original song, according to a White House official. The song was featured in the documentary “The Hunting Ground,” which deals with campus rape.

Biden will use the opportunity to promote the White House’s “It’s On Us” campaign against sexual assault, according to the official. The Obama administration launched the campaign last September.

Biden, who drafted the Violence Against Women Act as a senator, has long been outspoken on the issues of domestic and sexual violence.

It’s all about the optics.
